SYDNEY — A new technology that allows smartphones to identify strokes far quicker than existing methods has been developed by researchers in Australia.

The new technology uses artificial intelligence as it scans a patient’s face for symmetry and certain muscle movements, which are called action units. People who have suffered a stroke often have one side of their face looking different from the other.  

The biomedical engineers at Melbourne’s RMIT University say the smartphone technology can detect facial asymmetry, potentially identifying strokes within seconds – much sooner and more precisely than current technologies.

Professor Dinesh Kumar, who led the research team, explained to Australian Broadcasting Corp. how the AI-driven device works.

“It takes a video of a person who is doing a smile, and the model determines whether this particular smile is indicative of (a) person who has had a stroke,” Kumar said. “We then inform the paramedic or the clinician who is aware of the very high risk of this person having a stroke and, thus, can be treated immediately.”

Strokes affect millions of people around the world.  They occur when the supply of blood to part of the brain is interrupted or reduced, which stops brain tissue from receiving oxygen and nutrients.  Experts say that if treatment is delayed by even a few minutes, the brain can suffer permanent damage. 

Symptoms of stroke include confusion, speech impairments and reduced facial expressions.

The RMIT team reports that the smartphone tool has an accuracy rating of 82% for detecting stroke. They stress that it would not replace comprehensive medical diagnostic tests for stroke, but instead would guide initial treatment by first responders by quickly identifying patients who need urgent care.  

The Australian study, which was a collaboration with São Paulo State University in Brazil, is published in the journal, Computer Methods and Programs in Biomedicine.

BRUSSELS — European Union countries approved a flagship policy to restore damaged nature on Monday, after months of delay, making it the first green law to pass since European Parliament elections this month. 

The nature restoration law is among the EU’s biggest environmental policies, requiring member states to introduce measures restoring nature on a fifth of their land and sea by 2030. 

EU countries’ environment ministers backed the policy at a meeting in Luxembourg, meaning it can now pass into law. 

The vote was held after Austria’s environment minister, Leonore Gewessler of the Greens, defied her conservative coalition partners by pledging to back the policy — giving it just enough support to pass. 

“I know I will face opposition in Austria on this, but I am convinced that this is the time to adopt this law,” Gewessler told reporters. 

The policy aims to reverse the decline of Europe’s natural habitats — 81% of which are classed as being in poor health — and includes specific targets, for example to restore peat lands so they can absorb CO2 emissions. 

The move by Austria’s minister angered Chancellor Karl Nehammer’s conservative People’s Party, which opposes the law. The OVP minister for EU affairs, Karoline Edtstadler, said Gewessler’s vote in favor would be unconstitutional. 

Belgium, which holds the EU’s rotating presidency and chairs meetings of ministers, said the Austrian government dispute would not affect the legality of the EU ministers’ vote. 

EU countries and the European Parliament negotiated a deal on the law last year but it has come under fire from some governments in recent months amid protests by farmers angry at costly EU regulations. 

Finland, Hungary, Italy, the Netherlands, Poland and Sweden voted against the law on Monday. Belgium abstained. 

EU countries had planned to approve the policy in March but called off the vote after Hungary unexpectedly withdrew its support, wiping out the slim majority in favor. 

Countries including the Netherlands had raised concerns the policy would slow the expansion of wind farms and other economic activities, while Poland on Monday said the policy lacked a plan for how nature protection would be funded.

chicago, illinois — Vacationing in Chicago this week from Europe, Jelle den Burger and Nirusa Naguleswaran grabbed a bite at the Dog House Grill: a classic Italian beef sandwich for him, grilled cheese for her. 

Both think the way their genders lined up with their food choices was no coincidence. Women, said Naguleswaran, are simply more likely to ditch meat, and to care about how their diet affects the environment and other people. 

“I don’t want to put it in the wrong way, that male people feel attacked,” said Naguleswaran, of Netherlands, laughing. She said she used to love eating meat, but giving it up for climate reasons was more important to her. “We just have it in our nature to care about others.” 

Now, scientists can say more confidently than ever that gender and meat-eating preferences are linked. A paper out in Nature Scientific Reports this week shows that the difference is nearly universal across cultures — and that it’s even more pronounced in countries that are more developed. 

Researchers already knew men in some countries ate more meat than women did. And they knew that people in wealthier countries ate more meat overall. But the latest findings suggest that when men and women have the social and financial freedom to make choices about their diets, they diverge from each other even more, with men eating more meat and women eating less. 

That’s important because about 20% of planet-warming global greenhouse gas emissions come from animal-based food products, according to earlier research from the University of Illinois. The researchers behind the new report think their findings could fine-tune efforts to persuade people to eat less meat and dairy. 

“Anything that one could do to reduce meat consumption in men would have a greater impact, on average, than among women,” said Christopher Hopwood, a professor of psychology at the University of Zurich and one of the authors of the paper. The work drew on surveys funded by Mercy for Animals, a nonprofit dedicated to ending animal agriculture. Hopwood said he is not affiliated with the organization and is not an advocate. 

Researchers ask what thousands eat

The researchers asked over 28,000 people in 23 countries on four continents how much of various types of food they ate every day, then calculated the average land animal consumption by gender identity in each country. They used the United Nations Human Development Index, which measures health, education and standard of living, to rank how “developed” each country was, and also looked at the Global Gender Gap Index, a scale of gender equality published by the World Economic Forum. 

They found that, with three exceptions — China, India and Indonesia — gender differences in meat consumption were higher in countries with higher development and gender equality scores. 

The large number and cultural diversity of people surveyed is “a real strength of this,” said Daniel Rosenfeld, a social psychologist at UCLA who studies eating behavior and moral psychology and was not involved in the study. 

The study did not answer the question of why men tend to eat more meat, but scientists have some theories. One is that evolutionarily, women may have been hormonally hardwired to avoid meat that could possibly have been contaminated, affecting pregnancy, whereas men may have sought out meat proteins given their history as hunters in some societies. 

But even the idea of men as hunters is intertwined with culture, Rosenfeld said. That’s a good example of another theory, which is that societal norms shape gender identity from an early age and thus how people decide to fill their plates. 

‘I’m going to eat more’

Rosenfeld, who said he stopped eating meat about 10 years ago, said his own experience hanging out in college “as a guy hanging out with other guy friends” illustrated the cultural pressure for men to eat meat. “If they’re all eating meats and I decide not to,” he said, “it can disrupt the natural flow of social situations.” 

The same cultural factors that shape gender influence how people respond to new information, said Carolyn Semmler, a professor of psychology at the University of Adelaide in Australia who also studies meat eating and social factors such as gender. Semmler was not involved in this study. In some of her past work, she’s studied cognitive dissonance around eating meat. 

In those cases, she said, women presented with information about poor animal welfare in the livestock industry were more likely to say they would reduce their meat consumption. But men tended to go the other direction, she said. 

“One participant said to me, ‘I think you guys are trying to get me to eat less meat, so I’m going to eat more,'” she said. 

Semmler said meat can be important to masculine identity, noting for example the popular notion of men at the grill. And she said presenting eating less meat as a moral cause can be a sensitive issue. Still, she said, people should be aware of how their food choices affect the planet. 

But she and Hopwood acknowledged how difficult it is to change behavior. 

“Men are a tough nut to crack,” Hopwood said. 

Jose Lopez, another diner at the Dog House Grill, said he thought men should eat less meat but said that in general he has observed otherwise. 

“We’re carnivores,” he said. “Men eat like savages.”

NAIROBI, Kenya — Piles of firewood surrounded Jane Muthoni in her kitchen made of iron sheets. The roof, walls and wooden pillars were covered in soot. As she blew on the flame for tea, the 65-year-old was engulfed in smoke.

“I’ve used firewood all my life,” she said. “Sometimes I usually cough from inhaling the smoke, and my eyes itch, but there’s nothing I can do about it. I don’t have money to even buy charcoal.”

She was unaware of the lasting toll on her health. But experts are.

Respiratory diseases have been the most prevalent diseases in Kenya for the past several years and are on the rise, according to government authorities, with 19.6 million reported cases last year.

Burning biomass such as firewood is the largest contributor to those diseases, said Evans Amukoye, a scientist with the Kenya Medical Research Institute’s respiratory diseases research center.

“One can have itchy eyes, coughs while inhaling the smoke, and for serious cases like chronic obstructive pulmonary disease, you find that you cannot walk as your lungs have become tight,” Amukoye said. The disease is caused by indoor or outdoor air pollution or smoking.

Data from Kenya’s health ministry shows that chronic obstructive pulmonary disease is responsible for 1.7% of deaths in the country.

People in low-income areas are diagnosed with respiratory diseases later in life compared to middle-class people in urban areas with better awareness and access to health care, Amukoye said.

Families in informal neighborhoods and rural areas are the most affected as most people rely on firewood or fossil fuels for cooking. Women hunched over a smoking fire at stalls for tea or snacks is a common sight in the capital, Nairobi, and beyond.

The government’s 2022 Demographic and Health Survey showed a high dependence on traditional fuels for cooking in Kenya. The number of households relying on biomass like firewood increased from 4.7 million to 6.7 million between 2020 and 2022.

Economist Abraham Muriu said he believes the increase in Kenyans using firewood is a result of economic shocks caused by reduced incomes during the COVID pandemic and ongoing high inflation.

“Firewood is readily available and the most accessible fossil fuel, especially in rural areas,” Muriu said.

He said more Kenyans in urban areas have likely resorted to using firewood or charcoal, too, as prices and taxes rise. Blackened sacks of charcoal are openly on sale at some Nairobi intersections, and the hunt for firewood across the country is constant.

Mercy Letting, 33, a businesswoman in Nairobi’s Kasarani neighborhood was using charcoal to make meals for customers in the first six months after opening her restaurant early last year. With time, it affected her health.

“I am asthmatic, so whenever I used charcoal to cook the smoke would always trigger an attack, forcing me to spend part of my daily earnings on medication. This happened five times,” she said.

She found it expensive, spending 4,500 Kenyan shillings ($33) per month to buy a sack of charcoal. “I eventually had to buy an ‘eco-friendly’ cooker, which has been great for my health and good for business.” It requires less charcoal.

Letting also bought an induction burner, which she said is faster in cooking and more efficient as she spends only 50 Kenyan shillings ($0.38) per day on electricity.

Although companies pursue “clean cooking” options, high prices remain an obstacle to many Kenyans.

“If we want to deliver a truly clean and efficient solution to users across Africa, it needs to be affordable for them,” said Chris McKinney, the chief commercial officer at BURN Manufacturing, which describes itself as a “modern cookstove” company based on the outskirts of Nairobi.

“This has been the key barrier to scaling for us,” he said.

SAO PAULO — Thousands of demonstrators took to the streets of Sao Paulo on Saturday as protests sweep across Brazil in opposition to a bill that would further criminalize abortions. If passed, the law would equate the termination of a pregnancy after 22 weeks with homicide.

The bill, proposed by conservative lawmakers and heading for a vote in the lower house, would also apply in cases of rape. Critics say those who seek an abortion so late are mostly child rape victims, as their pregnancies tend to be detected later.

To rally opposition, rights’ groups created the ‘A child is not a mother’ campaign that has flooded social media. Placards, stickers and banners emblazoned with the slogan have abounded during demonstrations. And viral visuals depicting women in red cloaks compare Brazil to Gilead, the theocratic patriarchy Margaret Atwood created in her dystopian novel, The Handmaid’s Tale.

About 10,000 people, mostly women, filled several blocks of Sao Paulo’s main boulevard on Saturday afternoon, organizers estimated. It was the biggest demonstration yet, following events in Rio de Janeiro, Brasilia, Florianopolis, Recife, Manaus, and other cities.

Marli Gavioli, 65, has mostly refrained from protesting since demonstrations in the 1980s that called for the end of the military dictatorship, but she told The Associated Press she’s too outraged to remain home. “I couldn’t stay out of this, or I would regret it too much. We are being whipped from all sides, us women. It’s past time we do something,” she said.

Brazil only permits abortion in cases of rape if there is an evident risk to the mother’s life or if the fetus has no functioning brain. Aside from those exceptions, Brazil’s penal code imposes between one- and three-years jail time for women who end a pregnancy. Some Brazilian women fly abroad to obtain abortions.

If the bill becomes law, the sentence will rise to between six and 20 years when an abortion is performed after 22 weeks. Critics have highlighted that would mean convicted rapists could receive lesser sentences than their victims.

Experts say that late access to abortion reflects inequalities in health care. Children, poor women, Black women and those living in rural areas are particularly at risk.

“We cannot be sentenced to prison for having suffered a rape and not receiving support and care,” Talita Rodrigues, a member of rights’ group National Front against the Criminalization of Women and for the Legalization of Abortion, said by phone.

Of the 74,930 people who were victims of rape in Brazil in 2022, 61.4% were under 14 years old, according to a 2023 study of the Brazilian Forum on Public Safety, an independent group that tracks crimes.

“For children, it is common for a pregnancy to be discovered only after 22 weeks,” Ivanilda Figueiredo, a professor of law at the State University of Rio de Janeiro, said by phone. For example, they might not know that periods — a sign a woman isn’t pregnant — are monthly, she said.

Among the protesters in downtown Rio on Thursday was Graziela Souza, a 25-year-old student who was sexually assaulted as a child.

“I think it’s very important for victims to be present, as much as it hurts,” Souza said. “We must speak out and fight against it, because if we stay at home we are going to lose.”

Defenders of the bill have argued that abortions at a later stage were unimaginable when Brazil’s penal code was adopted in 1940, which explains why there is currently no time limit. Had it been envisioned, they argue, it would be considered infanticide.

The bill’s author, lawmaker and Evangelical pastor Sóstenes Cavalcante, declined an interview request from the AP.

On Wednesday, the lower house Speaker Arthur Lira rushed through a procedure to fast-track the bill in under 30 seconds, with many lawmakers reportedly unaware it was taking place. The maneuver allows the plenary to vote without the bill first clearing committees. Lira has been a top target for protesters’ ire. Signs on Saturday read “What if it happened to your daughter, Lira?” and simply “Lira out.”

Conservative lawmakers proposing the bill — who protesters have dubbed ‘the rape caucus’ — are playing politics, hoping to boost turnout and support from Evangelical voters in October municipal elections, Fernanda Barros dos Santos, a political scientist at the Federal University of Rio de Janeiro, said by phone. Abortion is a topic of high concern for Christians, who make up a majority of voters in Brazil.

“The bill puts people who are progressive in a very difficult situation, because they lose votes by defending abortion rights,” said Figueiredo, the law professor.

President Luiz Inácio Lula da Silva’s government has been seeking inroads with Evangelicals, a key voting bloc for far-right former President Jair Bolsonaro. Lula beat Bolsonaro in the 2022 presidential election.

“The president sent a letter to Evangelicals in the campaign saying he was against abortion. We want to see if he will veto it. Let’s test Lula,” Cavalcante, the bill’s author, told local news outlet G1 on Tuesday.

First lady Rosângela da Silva, known as Janja, slammed the proposal on social media Friday, saying women and girls who are raped need to be protected, not revictimized. Lula finally weighed in on Saturday, speaking at the G7 in Italy.

“I had five kids, eight grandchildren and a great-grandchild. I’m against abortion. However, since abortion is a reality, we need to treat abortion as a public health issue,” he said in a news conference. “And I think it’s insanity that someone wants to punish a woman with a sentence that’s longer than the criminal who committed the rape.”

Although strict abortion laws have long been the norm across the predominantly Roman Catholic region of Latin America, feminist movements have gained momentum in recent years and delivered successive victories for abortion-rights campaigners. Colombia’s Supreme Court decriminalized abortion in 2022, following a similar breakthrough ruling by Mexico. Argentina’s Congress legalized abortion in 2020, and a few years earlier Chile rolled back a strict ban.

athens, greece — A missing Dutch tourist was found dead early Saturday on the eastern Greek island of Samos, local media reported, the latest in a string of recent cases in which tourists in the Greek islands have died or gone missing. Some, if not all, had set out on hikes in blistering hot temperatures. 

Dr. Michael Mosley, a noted British television anchor and author, was found dead last Sunday on the island of Symi. A coroner concluded Mosley had died the previous Wednesday, shortly after going for a hike over difficult, rocky terrain. 

Samos, like Symi, lies very close to the Turkish coast. 

The body of the 74-year-old Dutch tourist was found by a Fire Service drone lying face down in a ravine about 300 meters (330 yards) from the spot where he was last observed Sunday, walking with some difficulty in the blistering heat. 

Authorities were still searching for four people reported missing in the past few days. 

On Friday, two French tourists were reported missing on Sikinos, a relatively secluded Cyclades island in the Aegean Sea, with less than 400 permanent residents. 

The two women, aged 73 and 64, had left their respective hotels to meet. 

A 70-year-old American tourist was reported missing Thursday on the small island of Mathraki in Greece’s northwest extremity by his host, a Greek-American friend. The tourist had last been seen Tuesday at a cafe in the company of two female tourists who have since left the island. 

Mathraki, population 100, is a 3.9-square-kilometer (1.2-square-mile) heavily wooded island, west of the better-known island of Corfu. Strong winds had prevented police and the fire service from reaching the island to search for the missing person as of Saturday afternoon, media reported. 

On the island of Amorgos, authorities were still searching for a 59-year-old tourist reported missing since Tuesday, when he had gone on a solo hike in very hot conditions. 

U.S. media identified the missing tourist as retired Los Angeles County Deputy Sheriff Albert Calibet of Hermosa Beach, California. 

Amorgos, the easternmost of the Cyclades islands, is a rocky 122-square-kilometer (47-square-mile) island of less than 2,000 inhabitants. A couple of years ago the island had a record number of visitors, over 100,000. 

Some media commentary has focused on the need to inform tourists of the dangers of setting off on hikes in intense heat. 

Temperatures across Greece on Saturday were more than 10 degrees Celsius (18 Fahrenheit) lower than on Thursday, when they peaked at almost 45 C (113 F). They are expected to rise again from Sunday, although not to heat-wave levels.

FORT LAUDERDALE, Florida — Although more rain could trigger additional isolated Florida flooding, forecasters say the strong, persistent storms that dumped up to 50 centimeters (20 inches) in southern parts of the state appear to have passed.

Some neighborhood streets in the Miami and Fort Lauderdale areas still have standing water, although it is rapidly receding, officials said.

“The worst flooding risk was the last three days,” said Sammy Hadi, a meteorologist with the National Weather Service in Miami. “The heaviest rainfall has concluded.”

The no-name storm system pushed across Florida from the Gulf of Mexico at roughly the same time as the early June start of hurricane season, which this year is forecast to be among the most active in recent memory amid concerns that climate change is increasing storm intensity.

Florida Governor Ron DeSantis held a media briefing in Hollywood, south of Fort Lauderdale, and said while more rain was coming, it’s likely to be more typical of South Florida afternoon showers this time of year.

“We are going to get some more rain today, maybe throughout the balance of the weekend. Hopefully it’s not approaching the levels that it was, but we have a lot of resources staged here, and we’ll be able to offer the state’s assistance,” he said.

DeSantis said the state has deployed about 100 pumps in addition to what cities and counties are using to try to clear water from streets.

Florida Emergency Management Director Kevin Guthrie said while flooding was extensive, there were no reports of destroyed homes and very few of severely damaged homes. No deaths or serious injuries have been reported.

“We don’t think there’s going to be enough damage to necessarily qualify for a federal disaster declaration,” DeSantis said. But he added the storms may have affected enough business to qualify for Small Business Administration assistance.

The downpours hit Tuesday and continued into Wednesday, delaying flights at two of the state’s largest airports and leaving vehicles waterlogged and stalled in some of the region’s lowest-lying streets. The main problem was hundreds of vehicles that were stranded on streets as people were unable to navigate the flood waters.

“Looked like the beginning of a zombie movie,” said Ted Rico, a tow truck driver who spent much of Wednesday night and Thursday morning helping to clear the streets of stalled vehicles. “There’s cars littered everywhere, on top of sidewalks, in the median, in the middle of the street, no lights on. Just craziness, you know. Abandoned cars everywhere.”

ABUJA, Nigeria — Traces of highly potent opioids known as nitazenes have for the first time been found to be consumed by people who use drugs in Africa, according to a report released Wednesday by the Global Initiative Against Transnational Organized Crime, a nonprofit organization.

Nitazenes, powerful synthetic opioids, have long been in use in Western countries as well as in Asia where they have been associated with overdose deaths. Some of them can be up to 100 times more potent than heroin and up to 10 times more potent than fentanyl, meaning that users can get an effect from a much smaller amount, putting them at increased risk of overdose and death.

The report focused on Sierra Leone and Guinea-Bissau and is based on chemical testing of kush, a derivative of cannabis mixed with synthetic drugs like fentanyl and tramadol and chemicals like formaldehyde. Researchers found that in Sierra Leone, 83% of the samples were found to contain nitazenes, while in Guinea-Bissau it was identified in 55%.

“The GI-TOC ( Global Initiative Against Transnational Organized Crime) believes that these results are the first indication that nitazenes have penetrated retail drug markets in Africa,” the report said.

Many young people in West and Central Africa have become addicted to drugs with between 5.2% and 13.5% using cannabis, the most widely used illicit substance on the continent, according to the World Health Organization.

In Sierra Leone where kush is one of the most widely consumed drugs, President Julius Maada Bio this year declared war on the substance, calling it an epidemic and a national threat.

Nitazenes have been detected repeatedly in substances sold to young people in the region such that users are most likely ingesting them “without knowing the risks they face,” Wednesday’s report said.

The authors said their findings suggest that nitazenes are being imported into Sierra Leone from elsewhere and that the substance being sold as kush in Guinea-Bissau was of similar chemical composition to that found in Freetown.

Officials in the two countries must deploy chemical testing equipment as a first step in tackling drug abuse, the report said. “Without this, it is impossible for the government of Sierra Leone, Guinea-Bissau and the wider subregion to accurately monitor the countries’ illicit drug markets and develop evidence-based responses,” it said.

MOGI GUACU, Brazil — Orange juice prices have always been volatile, falling when bumper harvests create an oversupply of oranges and rising when frost or a hurricane knocks out fruit trees.

But the record-high prices the world is seeing for OJ right now may be on the table for a while, since the diseases and extreme weather ravaging orange groves in some top-producing countries aren’t easily resolved problems.

This year’s harvest in Brazil, the world’s largest exporter of orange juice, is likely to be the worst in 36 years due to flooding and drought, according to a forecast by Fundecitrus, a citrus growers’ organization in Sao Paulo state.

“The concern isn’t just that the price of juice is going up. The concern is not having the juice,” Oscar Simonetti, an orange farmer in Mogi Guacu, Brazil, said.

In the U.S., Florida’s already diminished orange production fell 62% in the 2022-23 season after Hurricane Ian further battered a crop that was struggling due to an invasive pest. Drought also cut Spain’s orange production last year.

Scarce supplies have sent prices soaring. In the U.S., a 12-ounce can of frozen orange juice concentrate cost an average of $4.27 in April, 42% more than during the same month a year earlier, according to government figures.

In the United Kingdom, where the British Fruit Juice Association says supplies are at 50-year lows, the price of fresh orange juice rose 25% over the past year, according to consumer research company Nielsen.

Those price increases are turning off inflation-weary consumers. Orange juice consumption has fallen 15% to 25% in major global markets — including the U.S. and the European Union — over the last year, according to Rabobank, a Dutch bank that focuses on food and agriculture.

Jonna Parker, a principal for fresh food client insights at market research company Circana, said consumers are increasingly getting their morning fruit intake from energy drinks, smoothies and other beverages besides orange juice.

“The price gets high and people consider other alternatives,” she said.

Global orange juice consumption was already declining before the current price hikes due to competition from other drinks and public concern about the amount of sugar in fruit juices. If that trend continues, it should help balance supply with demand and keep prices from rising much further, Rabobank said. But it expects limited supplies will keep prices elevated for some time.

In some markets, orange juice is disappearing from shelves altogether.

Late last year, McDonald’s in Australia removed orange juice from its menu in favor of an “orange fruit drink” that contains 35% orange juice. The company cited short supplies.

Tokyo-based Morinaga Milk Industry Co. expects to stop shipping its Sunkist brand orange juice – which uses juice from Brazil – by the end of June because of low juice supplies from Brazil, a company spokeswoman said. In April 2023, Megmilk Snow Brand Co., based in the northern Japanese city of Sapporo, stopped shipments of 1-liter and 450-milliliter packs of orange juice, which it sells under an agreement with Dole. Sales haven’t yet resumed.

Some companies are considering using alternatives to oranges in their products. Coldpress, a British juice company, introduced a mandarin juice product in February, citing the high price of regular juicing oranges.

But others are tight-lipped about their plans. Several major orange juice makers – including Dole, Tropicana, Florida’s Natural, Uncle Matt’s and Coca-Cola, which makes the Simply and Minute Maid brands – declined to comment or failed to respond to inquires from The Associated Press.

The roots of the current supply troubles stretch back decades. In 2005, an invasive bug called the Asian citrus psyllid arrived in Florida, injecting bacteria from its saliva into the state’s orange trees. The bacteria slowly kills the tree by destroying its root systems. There’s no known cure once a tree is infected.

The impact has been devastating. In 2004, before the disease – called citrus greening – hit Florida, the state produced 200 million boxes of oranges. This year, it will produce less than 20 million.

Michael Rogers, a professor of entomology and the director of the University of Florida’s Citrus Research and Education Center, said no type of orange tree is totally resistant to greening, but scientists have been trying to breed trees that are more tolerant of it.

Citrus greening arrived in Brazil around the same time as Florida, but it has progressed more slowly there because Brazil has much larger orange groves. Bugs spread the disease by flying from tree to tree, Rogers said.

Still, the disease is spreading. Fundecitrus estimates that 38% of Brazil’s orange trees had citrus greening in 2023. Simonetti, the orange farmer, estimates that 20% of his production is affected by greening. Oranges on affected trees don’t ripen properly and fall off early, affecting the quality of their juice, he said.

Shifting production to other locations isn’t necessarily an option. California grows oranges, for example, and the citrus psyllid doesn’t fare as well in the state’s climate. But California also doesn’t get the rainfall needed for juicing oranges; its oranges are usually sold for eating, Rogers said.

Another issue impacting orange harvests is extreme weather, which is becoming more common as the world warms due to climate change.

Last year, nine heat waves swept across Brazil, resulting in lower output and poorer fruit quality. This year, the impacts of El Niño have been particularly dramatic, with a historic drought in the Amazon and devastating floods in the southern state of Rio Grande do Sul.

“The temperatures are high during the day. At night the temperature drops. The plant can’t stand this temperature difference,” Simonetti said.

Brazil’s 2024-25 harvest is expected to yield 232 million boxes of oranges, down 24% from the prior year.

“We have never seen a harvest like this,” Vinícius Trombin, the coordinator of Fundecitrus’ crop estimates survey, said.

To make up for the anticipated smaller yield, some producers are considering blending oranges with tangerines to make juice, Trombin said. But he’s skeptical.

“The consumer wants an orange juice made up 100% out of oranges,” he said.

Parker, of Circana, isn’t so sure. She thinks blends with other fruits might help hold down costs and revive consumer interest in orange juice.

“The idea of multiple flavors is very popular and is a way to stand out,” she said. “You’ve got to keep people engaged. Once you lose that interest, it’s really hard to get people back.”
